Abstract
Conductive cured products which have superior initial conductivity which is substantially retained even under high temperature and humidity conditions are obtained by curing a resinous composition comprising (a) a metallic copper powder, (b) a copper compound, (c) a compound having a 1,4-dihydroxy benzene ring or 1,2-dihydroxy benzene ring structure, and (d) a resinous curable component. Additionally, inclusion of a chelate forming compound in the uncured composition prevents a curing phenomenon on the surface of the composition during storage. The compound having the dihydroxy benzene ring (compound c) reduces the copper compound (b) to deposit metallic copper, and the resinous curable component integrates the constituents into a conductive product upon curing. The compositions are used as paints, adhesives, printing inks, and moulded articles, and they are useful in the electric, electronic, automobile, and housing fields.
